BACKGROUND

[0004] 1. Field of Invention

[0005] This invention relates to a four sided prism for the viewing ofone's own backside, as well as the normal frontal view and includingoblique front and back views, and which prism can be constructed as afixed structure or as a folding structure for saving floor space.

[0006] 2. Description of Prior Art

[0007] For centuries mirrors have been used to reflect the frontal imageof the viewer. Sometimes a viewer placed a mirror at their backside andin a position to reflect this oblique view into a mirror being held infront of them. In recent years mirrors have been provided in threeconnected frames to provide oblique front and side views. In somespecialty stores such as wedding gown departments mirrors have beenplaced on four walls of a small room to provide oblique front and rearviews and a full front view. These small rooms with their interior wallscovered with mirrors were not constructed as prisms. That is, they donot provide precise alignment of the reflective surfaces. The result isthe front, oblique and rear views of the viewer are distorted.

[0008] U.S. Pat. No. 226,362 was issued to Short showing four mirrorsarranged in a horizontal pattern, with the bottom two mirrors requiringadjustment in order for any person of a height different than theprevious viewer to see their backside. The mirrors presented in thepatent drawings would require a person of a different height than theprevious viewer to adjust the bottom two mirrors to see the top onethird of their backside. The viewer would be required to adjust thebottom two mirrors in order to see the middle section of their backside.The viewer would then be required to adjust the bottom two mirrors tosee the lower bottom one third of their backside. This patent does notprovide any oblique view of the front or backside of the viewer. Thispatent to Short covers an adjustable mirror array which, at best,requires many difficult adjustments by the viewer, and may require theassistance of two persons to adjust the mirrors for partial scanning ofthe backside of the viewer. The patent reveals a system which requiresinstallation in a fixed box, or portion of a home. All this atconsiderable cost of space and time requirements.

[0009] U.S. Pat. No. 370,623 to Hooker, U.S. Pat. No. 505,127 to Ranger,U.S. Pat. No. 533,167 to Fuller, U.S. Pat. No. 1,969,910 to Simjian,U.S. Pat. No. 2,379,214 to Bolinger, U.S. Pat. No. 4,050,790 to Jorwa,U.S. Pat. No. 6,252,730 to Chabot, and U.S. Pat. No. 6,322,222 toKobayashi all present an array of mirrors which offer some type of atleast partial view of the backside of the viewer.

[0010] All the reflective mirror or prism systems known to this datesuffer from a number of disadvantages.

[0011] (a) They do not offer a full scale image of the front, thebackside, the oblique front and the oblique backside image of theviewer. Our patent provides this.

[0012] (b) They offer no manufacturing system that allows totalprefabrication so that on-site installation can be completed in a mannerof minutes by one or two persons. Our patent provides this.

[0013] (c) They offer no indication of being suitable for mass marketingto the several million up-scale homes which qualify in space andfinancial status for such an appliance. None have reached any status asa mass produced commercial product. Our patent has survived a nationwide market analysis and manufacturing is being prepared to permit saleto homeowners nationwide.

[0014] (d) They offer no indication of being suitable for mass marketingto the several hundred thousand clothing stores which will find thisappliance of immediate value to their sales activities. Our patent hassurvived a nationwide market analysis and manufacturing is beingprepared to permit sale to clothing and department store operatorsnationwide.

[0015] (e) They indicate no ability to be disassembled as quickly asassembled and moved a short or a great distance for re-assembly in aprecision alignment status. Especially by one or two persons with notechnical skills in such assembly procedures. Our patent provides thisflexibility.

[0016] (f) They do not indicate any feature which allows forconstruction of the prism with hinges so the system can be foldedagainst a wall and covered by a cabinet for appearance and for floorspace conversation. Our patent provides this advantage.

OBJECTS AND ADVANTAGES

[0017] Accordingly, besides the objects and advantages of the precisionprism described in our above patent, several objects and advantages ofthe present invention are:

[0018] (a) A prism of such scale that a full sized person can walk intothe interior of the prism and review full scale images of their front,their back side, and oblique front and oblique backside views withoutany adjustments of the prism.

[0019] (b) A prism constructed of metal components for the frame, withmounts for the reflective surfaces, and which maintain perfect flatalignment of the reflective surfaces in their respective mounts, andmaintain perfect alignment of the relationship of one reflective surfaceto each and any of the other reflective surfaces.

[0020] (c) A prism which is assembled so that in the fixed model theprism can be assembled by one or two persons, in minutes, without use ofany hand tools.

[0021] (d) A prism which is assembled so that the fixed model the prismcan be surrounded by walls of a home or retail store without distortingthe alignment of the prism frame.

[0022] (e) A prism which is assembled so that in the folding model theprism can be attached to a wall and enclosed with a cabinet by one ortwo persons, in minutes, with minimum hand tools,

[0023] (f) A prism, fixed or folding, which can be disassembled, movedand reassembled easily, and remain in perfect alignment.

[0024] Further objects and advantages are to provide an appliance forviewing one's own backside which can be used as simply and convenientlyas a flat mirror, which is relative inexpensive to manufacture, which isextremely simple for anyone to assemble, and requires no adjustment atthe time of set-up or during use. Still further objects and advantagesof our invention will become apparent from consideration of the drawingsand ensuing description.

DETAILED DESCRIPTION

[0047] Description—FIG. 1—Fixed Position Prism System

[0048] A plan view of a prism system is generalized by a square formedby four frames (1), each supporting a mirror (2) and connect ed by shortcorner angles (3) in the opposite corners where the frames (1) cometogether, and long corner angles (4) where there is a separation of theframes (1). For the purposes of understanding, the scale of the frames,for this disclosure, are assumed to be four feet wide and, as shown inFIG. 2 are assumed to be seven feet tall. For the purposes of thisdisclosure, the square is assumed to be six and one half feet on a side.This square is formed about a reference line (5) running from one cornerwith short angles (3) to the opposite corner with short angles (3). Thisreference line (5) is important to the construction of the prism system.The 90 degree angle of the corners with short angles (3) are bisected bythis reference line (5). There is a second reference line (6) whichpasses through one corner with long angles (4) and through the oppositecorner with long angles (6). This plan view shows the frames (1) and theshort corner angle (3) holding the frames (1) in 90 degree angles toeach other, in close relation to each other, and the longer corner angle(4) holding the opposite frames (1) in 90 degree angles to each other,yet at a greater distance apart.

[0049]FIG. 2 is an elevation of the prism system looking into the prism.On the left of the FIG. 2 is a frame (1) supporting a mirror (2). In thecenter of FIG. 2 is the front surface of the mirror (2) on frame on thefar side of the prism. On the far right of FIG. 2 is a frame (1) withthe backside of a mirror (2) showing thru the frame (1). On the lowerleft and upper left of FIG. 2 are located the long angle corners (4). Onthe lower right and upper right corners of FIG. 2 are located the shortangle corners (3).

[0050]FIG. 3A is a plan view of the short corner angle (3).

[0051]FIG. 3B is a plan view of the long corner angle (4). There are atleast two alignment pins (7) in each side of each short corner angle (3)or each long corner angle (4). There are four each of the short cornerangles (3), two for the top and two for the bottom positions. There arefour each of the long corner angles (4), two for the top and two for thebottom. The spacing (8) between the alignment pins (7) on each arm ofthe angle is the same on both the short corner angles (3) and the longcorner angles (4). The distance (9) from the corner of the short angle(3) and the corner of the long angle (4) to the first of the twoalignment pines (7) varies with the final dimensions of the assembledprism system.

[0052]FIG. 4 is a plan view of the top or the bottom member of eachframe (1) in the fixed prism structure. The spacing (10) of the holes(11) are arranged the same distance from each corner. The plan view ofeach and all tops or bottoms of the frames (1) are identical. Thespacing (8) between the holes (11) are identical to the spacing betweenthe pins (7) on the corner angles.

[0053]FIG. 5A is a simplified plan view indicating only the front of themirrors (2) to define the shape and size of the prism, with the aid ofcross marks to define the theoretical corners (12) of this square prism.The second reference line (6) is drawn from the opposite theoreticalcorners (12) For purposes of clarity, the mirrors (2) are identifiedfrom left in a clockwise motion as first mirror (13), second mirror(14), third mirror (15), and fourth mirror (16). When a viewer (17)walks along the second reference line (6) from the lower left corner ofFIG. 6 toward the upper right corner until the viewer reaches a pointapproximating the center line (18) of the second mirror (14) and thesecond reference line (6). When the viewer (17) turns approximately 45degrees to the left and directly into the second mirror (14) the viewersees a full frontal image of her or himself. When the viewer (17) turnsan additional 45 degrees to the left the viewer is presented with a fullimage of her or his own backside. A reference arrow (19) along thebackside of the viewer is used to document the path of presentation ofthe backside of the viewer (17). On the fourth mirror (16) the referencearrow (19) rotates to the right. On the third mirror (15) the referencearrow (19) rotates further. On the second mirror (14) the referencearrow is further rotated. On the first mirror (13) the reference isagain rotated and positioned to properly present the full, accuratebackside of the viewer (17) for viewing by her or himself.

[0054]FIG. 5B—Oblique Rear Views of Viewer

[0055] When the viewer (17) moves to the centerline (54) of the firstmirror (13) and stands close to it, looking to the left along line (44),there is provided an oblique view of the rear right shoulder of theviewer. The sight of the viewer (17) is reflected off the first mirror(13) along line (45) to the fourth mirror (16). The sight of the vieweris then reflected along line (46) to the third mirror (15). From thethird mirror (15) the line of sight of the viewer (17) is reflectedalong line (47) to the second mirror (14). From the second mirror (14)the line of sight of the viewer is reflected to the right rear shoulderof the viewer.

[0056] When the viewer (17) looks to the right along line (49), there isprovided an oblique view of the left rear shoulder of the viewer. Thesight of the viewer (17) is reflected off the first mirror (13) alongline (50) to the second mirror (14). The sight of the viewer is thenreflected along line (51) to the third mirror (15). From the thirdmirror (15) the line of sight of the viewer (17) is reflected along line(52) to the fourth mirror (16). From the fourth mirror (16) the line ofsight of the viewer is reflected to the left rear shoulder of theviewer.

[0057]FIG. 5C—Front Left Oblique View

[0058] When the viewer (17) moves alone the centerline (18) of thesecond mirror (14) the viewer (17) looks alone line (56) to the secondmirror (14). The reflection of the line of sight is directed alone line(56) from the second mirror (14) toward the first mirror (13). The lineof sight is reflected from the first mirror (13) along line (57) to theleft front oblique view of the shoulder.

[0059]FIG. 5D—Front Right Oblique View

[0060] When the viewer (17) moves along the centerline (18) of thesecond mirror (14) and looks directly into the first mirror (13) alongline (58) the line of sight will be reflected along line (59) into thesecond mirror (14). The line of sight will be reflected along line (60)to the right front shoulder.

[0061]FIG. 5E—Expanded View of the Prism System

[0062] To expand the prism system to allow for viewing the backside ofone's own clothing when wearing a long bridal gown (61) is simple, asone knowledgeable in the art of optical physics will quickly see. Theprism started as a theoretical square, even when the frames (1) did notreach to the corners. The prism remains a theoretical square, even whenthe floor space for the expanded prism becomes a long rectangle. Theprism is divided along the original reference line (6) running from oneunconnected corner (12) to the other. The original reference line (5)running from the corner of first mirror (13) and the second mirror (14)to the corner of the third mirror (15) and the fourth mirror (16) isextended to the desired length. What is important is that the 45 degreeangles of the mirrors is maintained in relation to the reference line(5). Extending lines from the two sets of mirrors until they crossestablishes new theoretical corners (62). From these new theoreticalcorners (62) is established a new reference line (63) to replace thereference line (6). To keep the two sets of the mirrors in properrelationship the original long angle (4) used to connect the two sets ofmirrors has been cut at a 45 degree angle at the corner (64) of theframes (1,2,3,4). A long straight piece of metal tubing (70) of the sametype as the original long angle (4) is welded between the two shortenedpieces of the long angle (4). The viewer (17) looks along line (65) tothe first mirror (13). The line of sight is reflected from the firstmirror (13) to the second mirror (14) along line (66). The line of sightis reflected from the second mirror (14) to the third mirror (15) alongline (67). The line of sight is reflected from the third mirror (15) tothe fourth mirror (16) along line (68). The line of sight is reflected afinal time from the fourth mirror (16) to the backside of the viewer(17) along line (69), giving a full length view of the long bridal gown(61).

[0063]FIG. 6A—Folding Position Prism System

[0064] An elevation view reveals of the wall frame (20) for mounting thefolding prism system on the wall of a home or business. For the purposesof scale comparison to FIG. 1., the wall frame (20) is six and one halffeet from left to right, to match the fixed position prism design, butthis frame is only five feet tall. The second mirror (14) frame iscentered vertically on the wall frame. The left side of second mirror(14) is aligned so that the backside of the first mirror (13) is evenwith the left side of the wall frame (20) when the first mirror (13) isextended to its normal open position. On top of the wall frame (20) is aright angle bracket (43) which is level with the top of the secondmirror frame (14) when it is attached to the wall frame (20). Thisbracket serves as the pivot point mount for the 3^(rd) locking arm (43).

[0065]FIG. 6B—is a plan view of the wall frame (20) showing theextension arm (22) and the right angle bracket (43) pivot point for the3^(rd) locking arm (43).

[0066]FIG. 7 is an elevation of the revised third mirror frame (15),showing that the third mirror (15) in the folding prism system isattached by extension arms (33) to move the third mirror (15) into therelevant position of the prism square and defined in FIG. 1.

[0067]FIG. 8-A is a plan view of the folding prism system, including thewall frame (20) support, and showing the hinges for folding the mirrorsinto the stored position. The wall frame (20) is attached to whateverwall the owner has determined is suitable. The wall frame (20) isattached by strong bolts into the structure of the building throughholes (21) provided in the wall frame (20). The second mirror (14) isbolted to the wall frame (20) through bolt holes provided in bothframes. There is a first mirror (13) hinge (23) which is mounted onehalf on the first mirror (13) and one half one the second mirror (14).The first mirror (13) is placed in the relevant positioned with thesecond mirror (14) and the hinge pins common to all such large hingesare placed in position to make the hinge complete. In this plan view canbe seen the wall frame extension arm (22), with one half of the largehinge (24) mounted on the end of the extension arm (22). The thirdmirror frame (15) with it's extension arms has one half of the largehinge (24) mounted for attachment to the wall frame extension arm (22)hinge, allowing the insertion of the hinge pin to make the twocomponents into one. On the opposite end of the third mirror frame (15)is another hinge (25) half. On the appropriate end of the fourth mirror(16) is one half of the hinge (25), which mates with the opposite end ofthe third mirror (15) hinge (25). Again, inserting the hinge pin makesthe two components into one.

[0068]FIG. 8B is a plan view of the locking arm (26). There is a pivotpoint (42) for the fixed position of the locking arm (26). There is aslot (43) for the movement of the reference pin (44) on the movingmember which is being controlled by this locking arm (26). There is alocking arm cam (34) which retains the reference pin (44) at the extremeend of the locking arm (26).

[0069]FIG. 8C is a plan view of the locking arm cam (34). There is apivot point (35). There is a pressure pad (36). There is a flat cam (37)which allows the reference pin (44) to push the cam (34) sideways on thepivot point (35). There is a recess (38) which is the size of thereference pin (44) and is the stopping point for the locking arm (26).Pressure to force the system back into the folded position will causethe reference pin (44) to override the cam (37) lip.

[0070]FIG. 8D is a plan view of the locking arm cam stop (40), withanchor point (41) for attachment to the locking arm (26). There is apressure pad (39) equipped with any compressible spring or material toact against the pressure pad (36) on the locking arm cam 34.

[0071]FIG. 9 is a plan view of the folding prism system, in the storageposition. On top of the first mirror frame (13) and the second mirrorframe (14) is located a locking arm (26) which prevents the frames fromopening on the hinges to an angle greater than 90 degrees. On top of thethird mirror frame (15) and the fourth mirror frame (16) is locatedanother locking arm (27) which prevents these two frames from opening onthe hinges to an angle greater than 90 degrees. On top of the secondmirror frame (14) and the third mirror frame (15) is located a thirdlocking arm (42) which prevents these two frames from opening on thehinges to an angle greater than 90 degrees. Around this folded prismsystem can be built any type of cabinet for covering the folded prismsystem and which can be opened for extension of the prism system for useby the viewer (17).

[0072] Advantages

[0073] From the description above, a number of advantages of our prismfor viewing one's own backside become evident.

[0074] (a) The view of the backside of one's own self is seen asdirectly from the backside, and not from oblique or distorted view

[0075] (b) The views of one's frontal image and backside images are fullscale.

[0076] (c) The use of the prism does not require any adjustments

[0077] (d) The prism can be housed within a small room withoutattachment to or structural support from the building

[0078] (e) The prism can be built so as to be capable of folding into aflat configuration, allowing for the enclosure of a decorative cabinetto cover the folded prism, all in a narrow floor space.

[0079] (f) The fixed prism can be assembled by one or two persons inminutes without use of hand tools.

[0080] (g) The folding prism can be a attached to the wall of a buildingby one or two persons in minutes, requiring only hand tools for boltingthe wall mount to the wall of the building, and a wrench to bolt thesecond mirror to the wall frame.

[0081] (h) Both prisms can be disassembled as easily as assembled, andwhen reassembled they are precisely arranged for proper presentation ofthe respective views.

[0082] Operation

[0083]FIG. 5A—Fixed prism system Shows the simplicity of the use of theprism for viewing one's own backside. The viewer enters thru the passageway afforded by the space between the first mirror (13) and the fourthmirror (17). The viewer turns 45 degrees to the left and sees their fullscale, direct line of sight frontal image. The viewer turns anadditional 45 degrees to the left and they see their full scale, directline of sight backside image. There us no adjustment of the prismrequired or permitted by this invention.

[0084]FIG. 9—Folding prism system shows the simplicity of converting thefolded prism system from the stored to the full use version. If thereare decorative cabinets built around the folding prism system, the doorsto such cabinets would be opened to permit free and full access to thestored prism system. The viewer grasps the third mirror (15) about thevertical middle section and slowly swings the third mirror (15) and thefourth mirror (16) to the right, on the hinges until the locking arm(42) stops the motion of the fourth mirror (16) in the 90 degree angleto the second mirror (14). The viewer then grasps the fourth mirror (16)at about the middle vertical section of the free swinging end and slowlypulls the fourth mirror (16) until the locking arm (27) stops the motionof the fourth mirror (16) in the 90 degree angle to the third mirror(15). The viewer then grasps the free swinging end of the first mirror(13) at about the middle vertical section and slowly swings the firstmirror (13) on its hinges until the locking arm (26) stops the motion ofthe first mirror (13) in the 90 degree angle to the second mirror (14).The viewer then steps through the clearance between the first mirror(13) and the fourth mirror (16) and turns 45 degrees to the left to seetheir full frontal image. The viewer then turns an additional 45 degreesto the left and sees their full backside image. To close the foldingprism system, the viewer reverses the simple opening procedure exactlyand the prism is returned to the full folded position.

[0085] Conclusion, Ramification, and Scope

[0086] There is prior art which reveals interest in the solution of howto view the backside of one's own body, hair, or clothing. The patent toShort demonstrates a fundamental application for partial viewing, oreven if full viewing, of one's backside, with the provision that thebottom two mirrors be adjusted every time a person of a different heightthan the last viewer uses the system. In some retail clothing storesthere are small rooms used for examination of clothing, especiallywedding gowns. The walls are covered with mirrors. None of these roomswere discovered to be constructed in the form of a theoretical square.The results in every case of over one hundred such examination roomsavailable was that there was no full scale backside presentation of theviewer. Without except, these mirror covered rooms presented oblique ofdistorted front and backside views of the viewer. Other technicaldevices offered interesting inventions, but none offered the ability ofthe invention revealed in this patent application.

[0087] The invention disclosed herein is unusual in that in a field ofprior art, although somewhat limited, this invention is not preceded byany prior art for a full sized prism, capable of being entered into by afull grown human being, rendering a full scale front view of the viewer,or a full scale view of the backside of the viewer, or oblique views ofthe front or the backside of the viewer. Even with adjustments allowedby their disclosures, they did not provide the results if thisinvention.

[0088] The scope of this invention is for a device which has no priorart in the field of devices for viewing the full scale front side andthe full scale backside of one's own body, without adjustments orassistance of others.
